Harvard University professors constantly read and assign texts to their students. So they know a good book when they see one.

With that in mind, Business Insider asked professors at Harvard to share the single book they think every student should read in 2018.

The professors include Nobel laureates, scientists, economists, and Pulitzer Prize winners. The books they chose were as diverse as their professional backgrounds.

Read on to see what professors from Harvard think you should read next year.

'Anna Karenina,' by Leo Tolstoy

Amazon

"I'm re-reading 'Anna Karenina.' There is no better novel I know about how women (and I don't mean just Anna) - elite, intelligent, educated - are ignored, oppressed, and have little legal recourse. Women are the caregivers, the empathetic. They hold society together and provide salvation even as the priests take the credit.

"Tolstoy's novel is as relevant today as it ever was. As a sideline, one also learns about technical change in agriculture and how to incentivize laborers to adopt it. And there is more … It is clearly the best novel ever written and worth another close read from us all."

'The Internationalists,' by Oona Hathaway and Scott Shapiro

Amazon

"'The Internationalists,' by the legal scholars Oona Hathaway and Scott Shapiro, explain a phenomenon you probably didn't even know existed — the decline of interstate war and conquest — with a historical event you probably think is ridiculous: the Kellogg-Briand Paris Peace Pact of 1928, which declared war illegal.

"But in their gripping and evidence-rich book, they make a plausible case. And like The Clash of Civilizations and The End of History, the book presents a sweeping vision of the international scene, making sense of many developments in the news and recent history."
